What should I learn to create a basic OCR project in Python OpenCV?
Learn basics of tesseract ocr and open cv with python and try some simple projects like data extraction from images with ocryou can google it and you will get more is very interesting concepthappy code
Is there any Python package that I can use for scanning a receipt and parsing its data?
There various approaches to achieve this end result but there a few high level blocks here Acquire an to make it OCR-worthy wrinkles and folds 1 handwritten markings (did you add the tip? all those heart signs with ae again) 1 OCR the (easier said than done) The date could be a footnote or in between lines of other (think about server name on a restaurant bill versus a gas receipt) 1 Interpreting the OCRed A receipt follows very different grammar than the English language. Only the alphabets and numerals are the same the language ispletely different even from store to store or across printer models. Where does the itemized list begin? 1 Items sold by weight? 1 tax rate codes 1 The rest of it should beparatively easy - just dump everything in a database. library Tasseract but there many others a google struggle should get you the one you need for each step above.
How do I make a JAVA based OCR?
Have you tried tesseract-ocr - An OCR Engine that was developed at HP Labs between 1985 and 1995... and now at Google. - Google Project Hosting s ?
What is the difference beween OpenFace, OpenCV and OpenBR?
OpenCv.. OpenBR and OpenFace are all Computer vision frameworks they serve different purpose but they're all OpenSource libraries. OpenCv OpenCv is the most powerfulputer vision library among BR and Face. OpenCv is not only related to Image recognition it can be used to build other cool stuff related toputer vision. You can build a range of projects using Open CV ranging from applying a filter to your photos OCR detection from livestream Video frames etc. You can also build face recognition modules by training your own data sets. But OpenCv isn't fullypatible with Nueral networks. It contains more than 2 Algorithms. OpenFace OpenFace makes use of Deep Nueral networks to implement face recognition. OpenFace is basically a python implementation. Many pertained models are available for use. OpenFace is really simple to use. You can create a recognition. You can build your own recognition model on top of it rather than building from scratch. Training Nueral nets is aputationaly intensive task. So Google cloud offers you their TPUs to build a model on the cloud. Narasimha1997 s . I just built a project using inception 3 it can recognise almost all using my phone and get back the result. I'm planning to build a demo app which makes use of this server for image recognition. One of the main advantage of Building servers for AI is that.. it mainly reduces your application size you can concentrate on other features to add and your app can work faster. If you are planning to build a simple Ocr face tracking application you can go for Google mobile vision. Its really simple and lightweight. Follow this Mobile Vision | Google Developers s .

What are the languages they use in the computer vision industry?
MATLAB is good for rapid prototyping and proof of concept implementations. However realputer vision systems require a significant amount of software (and in some cases hardware) plumbing around theputer vision algorithms themselves to turn them into a usable product or technology. So naturally product requirements and the programming platform used to develop the host software dictate the language used to implementputer vision. nI have seenputer vision algorithms in C++ and OpenCV for products with low latency constraints with the software itself developed in a popular technology like JAVA that interfaces with C++ via Java Native Interface (JNI). For products whereputer vision is used for offline processing without tight latency considerations Python (with Numpy and cv2 bindings to OpenCV) or JAVA (with javacv bindings to OpenCV) are good choices.
